Chinese researchers found a polysaccharide (LHP) from Lactarius hatsudake mushrooms that potently inhibits liver cancer. In mice, high-dose LHP (500 mg/kg) reduced tumor volume by 73%, comparable to cisplatin (75%) but without toxicity. In cell studies, LHP at 1.6 mg/mL decreased cancer cell survival to 61.94% and colony formation to 53.77%. It induced apoptosis (3.40% at 1.6 mg/mL) and reduced invasion ability by 54.78%.
